MANGLE Specification of Letters Patent.

Patented March 31, 1908.

Application filed April 29, 1901. Serial No. 370,792.

To all whom it may concern): Be it known that I, LEWIS H. SLAGHT, of the city of Toronto, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Mangles, of which the following is a specification.

This invention relates to improvements in mangles of the type in which the goods are first ironed between padded rolls and concave steam chests and then re-ironed on the same side bybeing drawn over the smooth bottoms of the steam chests.

My object is to devise a mangle of this ty e which will have a great capacity for wor that will iron the clothes equally on both sides; that will consume a minimum of steam for heating; that will occupy a small amount of floor space; and that will be cheap to construct.

I achieve my object by using two sets. of rollers and steam chests one above the other. The clothes after being passed'between the first set of rolls and chests are carried back in contact with the under side of the chests. Thence the clothes are carried through the hot space between the two sets and are treated by the second set, being finally dis-.

charged fromthe machine'at the opposite end to that at which they were fed in.

The extra evaporation obtained by running the goods through the 0 en space be tween the sets enables the machine to be run at a faster rate of speed than the ordinary proved mangle showing also, in dotted lines,-

the rollers, steam chests and aprons. Fig. 2

In the drawings like letters of reference indicate corresponding parts in the different figures.

- manner. gear wheel 7 secured to the end of its spindle.

Referring particularly to Figs. 1 and 3, 1 are the end frames of the machine. Each end frame is preferably sectional, that is divided on the line 2 so that further sections may be inserted for the purpose of introducing a larger number of rolls and steam chests into the machine.

Between the end frames are supported two sets of mangling rollers and steam chests, arranged oneover the over. Inthe drawings I illustrate three upper steam chests 3;

rollers 5, and three lower rollers 6., T ese steam chests are of the ordinary type, concave above to fit t e rollers, and flat below, and are set side by side to form practically a continuous lower surface from end to end of the machine. v

The rollers may be driven in an suitable I show each roller provi ed with a The threegear wheels of each set of rollers are geared together by means of the intermediate gear pinions 8. Thus the rollers in each set may be caused to revolve in the same direction; On the spindle of one of the upper pinions 8 is secured a gear wheel't), w

ich-meshes with a similar gear wheel 10, v

secured to the spindle of one of the lower pinions 8. 1 Thus the lower rollers may be caused to revolve in the opposite direction to the upper rollers. This gear wheel 10 meshes with a gear inion 12 fast on the driving shaft 13. It will the gears 7 and 8 are duplicated on the oppo site side of the machine, the s indles 11 of the inions 8 extending from side to side.

three lower steam chests 4; three u per be understood, of course, that 7 T16 driving shaft may be provided with I any suitable driving means. I show two driving pulleys 14 thereon of different diameters to give different speeds. These pulleys, as is usual, will be loose on the shaft, and either may be given a drivin connection therewith by means of a c utch 15, which, being of ordinary construction, is not illustrated in detail.

Beneath theu per series of steam chests is located an end ess apron 16. passes around the rollers 17, so arranged that the up er surface of the belt is in close contact with the under surface of the series of steam chests, and also in contact with the end of the right end steam chest, as seen articularly in Figs. 1 and 3. One of the re lers 17 may be provided with screw adjustments This apron on the frame, as indicated at 28, whereby the tension on the apron may be adjusted as necessary, but I may employ in addition, or as a substitute, the loose roller 44.- hich lies in a bight of the apron and automatically takes up all slack.

When the machine is operation the goods operated on are first ironed between the rollers and the concave upper surfaces of the steam chests, and are then caught by the apron 1t and carried back to the end of the machine which they entered beneath the under surfaces of the steam chests against which they are given a second ironing on the sameside of the goods. The apron 16 delivers the goods on to the endless apron 19 which passes around the rollers 20. This apron is caused to travel in the opposite direction to the endless apron 16, consequently 'its upper part is traveling in the same direction as the lower part of the apron 16. The goods are thus can ht between the two aprons 16 and 19 at t e left hand side of the machine Fig. 3which is the feedin sideand caused to travel back towards tie ri ht hand side of the machinewhich is the do ivery sideon top of the upper part of the apron 19, and after the beginning of their travel out of contact with the apron 16. The a ron 19, it will be seen, is led to a point suitab le to deliver the goods upon the ri ht hand lower roller'6. A uide 21 is preferably provided to guide t e goods properly between the roller and its cooperating steam chest.

It will be noted that the goods have been carried from the feed to the delivery end of the machine by means of the apron 19 through the highly heated space between the two sets of mangling rollers and steam chests after treatment by the first set of apparatus and before treatment by the second. As the goods on the apron are out of contact with any solid part of the apparatus duringthis part of their course evaporation takes place entirely unchecked owing to the free escape thus rovided for the Water vapor, and owing to the fact that it is the unironed surface of the goods which is uppermost and it is to this surface the remaining moisture has been driven by the contact of the goods with the heated steam chests of the upper set. This arrangement permits of the machine being speeded up to a point not permissible with machines of the ordinary type containing the same number of rolls.

It will be noted that the apron 19 is carried around under the lower surfaces of the lower steam chests in a manner similar to that in which the a ron 16 is carried under the upper steam 0 sets 3. The apron is, however, in contact with the outer side of each end steam chest. This secures for me a very great increase in the available heatin surface of the steam chests, and I am enabled ame) F? to gain this extra heating surface by the arrangement of the manghng rollers and steam chests in two tiers, as described.

The goods fed to the right hand lower roller pass back to the feed end of the ma chine between the lower rollers and I their steam chests and are caught again by the apron 19, and are treated to a second ironing on the same side between the apron and lower surfaces of the lower steam chests. The goods are then carried out of the machine at the right hand or delivery end of the machine. Althou h this apron 19 is formed as a single apron it is in fact equivalent to two aprons, one above the lower rollers conveying the goods received from the apron 16 to the lower right hand roller 6, and a second apron receiving the goods from the lower left hand roller 6 and conveying them back to the delivery and of the machine. 7

it will be noted that it is desirable to provide one of the rollers 20 with a screw adjustment 22 on the frame of the machine for adjusting the tension of the apron 19, and

also to provide the apron with a loose roller 1 l5 operating in the same manner as the roller 4A.

I have alreadstated that mv machine may be opearted at a higher rate of speed than ordinary machines containing the same number of rollers. It is, however, found in practice that operators cannot feed oods to or on to surfaces traveling at a speed greater than, say for example, sixty feet per minute. As my machine is adapted to operate at a considerably greater speed I have found it necessary to devise means whereby the operator can successfully feed the machine. For this purpose I provide a feeding apron 23 which is carried by the rollers 24, and is suitably located todeliver between the left hand upper roller 5 and its steam chest 3. This feeding apron will be driven at the same rate of speed as the mangling rollers. (See Fig. 2). A second feeding apron 25 is carried by the rollers 26, and is adapted to deliver on to the feeding apron 23. This apron may be driven. at a considerably lower rate of speed than the apron 23. On this apron the goods may be fed by the operator without any difficulty owing to its comparatively slow rate of movement. As soon, however, as the goods reach the faster traveling feeding apron 23 they 'are carried rapidly away into the machine leaving the slower moving feeding apron clear for the aperator. The endless aprons 163, 19, 23 and 25 are driven in the manner '1 will now describe.

To the spindle of one of the lower pinions 8 l secure a sprocket wheel 36 which is connected by means of a sprocket chain with a sprocket wheel 37 fast on the s indle of the upper left hand roller 17 of t e apron 16. 1g. 1). The lower apron 19 may be simisprocket wheel isconnected, by means of asprocket chain, with the sprocket wheel 39 and lower sets of rollers.

on the spindle of the upper left hand roller 20 of the apron 19. v

The rollers 'carr ing the feed aprons 23 and 25 may be geare together by means of the gear wheels 40, 41 of a suitable proportion to give the outer apron 25 the desired speed. On the same spindle as the 1 car wheel 41, but preferably at the other side of the machine, is a sprocket wheel 42, driven by a sprocket chain from the sprocket Wheel 43 on the spindle of one of the upper pinions 8. All sprocket wheels will, of course, be suitably proportioned to drive the aprons 16, 19 and23 at or about the speed of the surfaces of the rollers.

When the mangle has finished its work it is desirable that the rollers shall be lifted from their steam chests to avoid scorching the textile coverings which are usually applied to and wrapped around them when the machine is in use. Each roller therefore is provided at each end with a journal block 27 slidable in a vertical slot 28. Vertical rods 29 connect the journal blocks of the up er Each rod is a so referably provided with a turn-buckle 30 or suitably adjusting the length. (See Fig. 4). The lower blocks 27 are engaged by vertical rods 31 lon itudinally movable, and adapted at their Iower ends to engage the straps of eccentrics 32, secured to the shaft 33, suitably journaled on the frame of the machine. This shaft is preferably operated by worm gearing 34, which may be operated in any suitable manner to rotate the shaft 33 to cause the eccentrics 32 to lift the rods 31, and thus through the connections already described raise the rollers of each set away from their steam chests. Sufficient scope of movement is rovided to enable the rollers to be raised suf ciently far to draw the gear Wheels 7 out of mesh with the pinions 8. Each roller may thus easily be rotated to strip its textile coverin' from it. Each of the vertical rods 31 shou d be provided with a turn -buckle 35, or other means of adjusting its length, to properly engage the eccentrics 32. a

A machine constructed as I have described ossesses many important advantages. t will be seen that each side of the goods is twice ironed, and as the sides are thus treated alike it is unnecessary for the operator to lose time in placing the goods right side up at thefeed. As the goods are given a drying between the two steps in the process the machine may be spee ed considerably above machines of the ordinary type.

By the arrangement of the mangling apparatus in two tiers I secure increased 1ron1ng surface over other mangles containing a similar number of rollers. TlllS construction also considerably shortens the length of the ma chine, and this results in the shortening of the aprons, and short aprons will hold the goods much tighter against the bottom surface of the steam chests than long aprons, thereby obtaining better results in ironing, as well as eliminating the trouble experienced by long aprons sagging and running out of line. The steam chests being arranged in two tiers economizes the heat, and the steam chests may thus be maintained at a suitable ironing temperature with a lower steam pressure thereb economizing fuel and rendering the chests less liable to leak.

I What I claim as my invention is:

1. In a mangle the combination of a steam chest and a cooperating roller; an apron adapted to take goods from the roller and draw them back to. the feed end of the apparatus against the underside of the steam chest; an apron adapted to receive the goods from the aforesaid apron and carry them back to the delivery end of the apparatus outv of contact with the aforesaid steam chest; a second steam chest and cooperating roller adapted to receive the goods from the last mentioned apron and deliver them at the feed end of the machine; and an apron adapted to take the goods from the roller and draw them back to the delivery end of the apparatus against the underside of the steam chest.
